Film-forming structure: It utilizes micron-scale film-forming polymers to create a breathable, flexible, low-refractive-index micro-mesh film on the skin's surface rather than an occlusive coating. This achieves a soft-focus effect through diffuse reflection while delaying sebum oxidation to prevent makeup from wearing off or becoming dull.
Powder and porous structure: A porous structure is created using components such as modified starch microspheres (3–8 microns) and silicone elastomers. With a controlled thickness of 0.015–0.025 mm, the foundation dynamically absorbs excess oil while maintaining moisture balance in the stratum corneum, preventing dryness or creasing.
Synergistic ingredient structure: A composite system combining oil-absorbing agents, film-formers (comprising 8%–12% of the formula), and moisturizing ingredients strikes a balance between oil control, long-lasting wear, and skin feel, avoiding the heavy, cakey finish that results from relying solely on high concentrations of oil-absorbing powders.
